West Nile Virus

 What is West Nile Virus?

West Nile is a mosquito-transmitted virus. Most people infected with West Nile virus either don't develop signs or symptoms or have only minor ones, such as fever and mild headache. However, some people develop a life-threatening illness that includes inflammation of the spinal cord or brain. Mild signs and symptoms of a West Nile virus infection generally go away on their own. But severe signs and symptoms — such as a severe headache, fever, disorientation or sudden weakness — require immediate attention. See Additional Resources below for links to additional information.

Summit County Mosquito Control Program

West Nile Virus is endemic to Summit County and detecting the virus during County trapping activities is a common occurrence. It is common for spikes to occur in late summer and into the fall (end of July/early August). To date, there have been no human West Nile virus cases in Summit County this year or last.  

Summit County Public Health (SCPH) provides information to the public on matters such as mosquito ecology, vector-borne disease information, proper cultural practices for mosquito larva reduction, and mosquito control methods used by the Mosquito Control Program.
